Abstract
We use data from the Annual Survey of Manufactures to study the characteristics and geography of investments in robots across U.S. manufacturing establishments. We find that robotics adoption and robot intensity (the number of robots per employee) is much more strongly related to establishment size than age. We find that establishments that report having robotics have higher capital expenditures, including higher information technology (IT) capital expenditures. Also, establishments are more likely to have robotics if other establishments in the same Core-Based Statistical Area (CBSA) and industry also report having robotics. The distribution of robots is highly skewed across establishments’ locations. Some locations, which we call Robot Hubs, have far more robots than one would expect even after accounting for industry and manufacturing employment. We characterize these Robot Hubs along several industry, demographic, and institutional dimensions. The presence of robot integrators and higher levels of union membership are positively correlated with being a Robot Hub.

30 Years after Reunification, Gross Domestic Product has Served its Purpose as an Indicator
Oliver Holtemöller
Wirtschaftsdienst,
Konferenzband "30 Jahre Deutsche Einheit", März
2021
Abstract
The comparison of living conditions in East and West Germany is often based on the gross domestic product per inhabitant. However, this measure is not a good welfare indicator in itself. It can be assumed that, measured by the gross domestic product per inhabitant, there will be no further significant equalisation of economic power in East and West Germany in the foreseeable future. This is because the age structure of East Germany, i.e. the ratio of employed persons to inhabitants, is less favourable than in the West. On the other hand, if one looks at important welfare indicators such as consumption opportunities, life expectancy, leisure time and income inequality, living conditions in East and West Germany are more similar than the gross domestic product per inhabitant suggests. In the debates on the catching-up process of East Germany, more emphasis should therefore be placed on labour productivity as a measure of economic strength and on welfare indicators as a measure of the equalisation of living conditions.

Trade, Misallocation, and Capital Market Integration
Laszlo Tetenyi
IWH-CompNet Discussion Papers,
No. 8,
2019
Abstract
I study how cross-country capital market integration affects the gains from trade in a model with financial frictions and heterogeneous, forward-looking firms. The model predicts that misallocation among exporters increases as trade barriers fall, even as misallocation decreases in the aggregate. The reason is that financially constrained productive exporters increase their production only marginally, while unproductive exporters survive for longer and increase their size. Allowing capital inflows magnifies misallocation, because unproductive firms expand even more, leading to a decline in aggregate productivity. Nevertheless, under integrated capital markets, access to cheaper capital dominates the adverse effect on productivity, leading to higher output, consumption and welfare than under closed capital markets. Applied to the period of European integration between 1992 and 2008, I find that underdeveloped sectors experiencing higher export exposure had more misallocation of capital and a higher share of unproductive firms, thus the data is consistent with the model’s predictions. A key implication of the model is that TFP is a poor proxy for consumption growth after trade liberalisation.

History, Microdata, and Endogenous Growth
Ufuk Akcigit, Tom Nicholas
Annual Review of Economics,
2019
Abstract
The study of economic growth is concerned with long-run changes, and therefore, historical data should be especially influential in informing the development of new theories. In this review, we draw on the recent literature to highlight areas in which study of history has played a particularly prominent role in improving our understanding of growth dynamics. Research at the intersection of historical data, theory, and empirics has the potential to reframe how we think about economic growth in much the same way that historical perspectives helped to shape the first generation of endogenous growth theories.

East Germany Three Decades After the Wall Came Down: What has Been Achieved and What Should Economic Policy Do?
Reint E. Gropp, Gerhard Heimpold
Wirtschaftsdienst,
No. 7,
2019
Abstract
The persistent difference in productivity between East and West Germany not only results from the relative absence of large firms based in the East as many believe. Companies of all sizes exhibit an East-West productivity gap. The gap is larger in urban regions. Scarcity of skilled labour has emerged as the new barrier to business development. In order to boost productivity, economic policy should avoid additional subsidies that are conditional on creating jobs. Additionally, the potential of East German urban areas should be better explored. Mitigating the shortage in qualified workers requires in-migration of skilled labour from abroad, supported by an open mindset and environment.

Innovation and Top Income Inequality
Philippe Aghion, Ufuk Akcigit, Antonin Bergeaud, Richard Blundell, David Hemous
Review of Economic Studies,
No. 1,
2019
Abstract
In this article, we use cross-state panel and cross-U.S. commuting-zone data to look at the relationship between innovation, top income inequality and social mobility. We find positive correlations between measures of innovation and top income inequality. We also show that the correlations between innovation and broad measures of inequality are not significant. Next, using instrumental variable analysis, we argue that these correlations at least partly reflect a causality from innovation to top income shares. Finally, we show that innovation, particularly by new entrants, is positively associated with social mobility, but less so in local areas with more intense lobbying activities.

What Type of Finance Matters for Growth? Bayesian Model Averaging Evidence
Iftekhar Hasan, Roman Horvath, Jan Mares
World Bank Economic Review,
No. 2,
2018
Abstract
We examine the effect of finance on long-term economic growth using Bayesian model averaging to address model uncertainty in cross-country growth regressions. The literature largely focuses on financial indicators that assess the financial depth of banks and stock markets. We examine these indicators jointly with newly developed indicators that assess the stability and efficiency of financial markets. Once we subject the finance-growth regressions to model uncertainty, our results suggest that commonly used indicators of financial development are not robustly related to long-term growth. However, the findings from our global sample indicate that one newly developed indicator—the efficiency of financial intermediaries—is robustly related to long-term growth.
